Actually, there is another mineral that shares quartz's structure, and it is not even a silicate. It is a rare phosphate named berlinite, AlPO4, that is isostructural with quartz. The structure of quartz involves corkscrewing (helix) chains of silicon tetrahedrons.

Chemistry: Mg3Si4O10(OH)2, Magnesium Silicate Hydroxide Mineral specimens are not very common as it does not form very large crystals. However, it often replaces other minerals on an atom by atom basis and forms what are called pseudomorphs (false shape). The talc takes the form of the mineral it replaces.

Chrysotile is not a single mineral, but a group of polymorphous minerals with the same chemical composition but different crystal lattice. Basic silicate of magnesium, iron, aluminum, nickel, zinc, and manganese. (Some rare varieties contain water in place of the hydroxyl, and substitute a different metal in exchange...

Press release: the 'BG Top Ten' products from 2003 Mineral silicate paints are not new, but they will be new to many in North America, including most of those in the green building industry. Keim Mineral Systems invented mineral silicate paints in Bavaria (Germany) in 1878, and Keim paints are used around the world today.
